TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No. 536,900, dated April 2,1895. Application filed November 28,1894. Serial No. 530,269. (Nomodel.)

To all whom it may concern..-

Be it known that I, HENRY TRos'r, a citizen of the United States,residing at Cohoes, in the county of Albany and State of New York, haveinvented certain new and useful improvements in Type-Writer Cabinets;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which "1 o it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the igures of referencemarked.

zo will be carried, down into thc cabinet when the top to the cabinet isto be closed and carried up to a horizontal position when the top isthrown back and into the 'interior of the.

cabinet. A Y

To the accomplishment of the foregoing and such otherobjects as mayhereinafter appear the invention consists in the construction and thecombination of'parts hereinafter particularly described and then soughtto be 3o specifically defined by the claims.

In the drawings Figure 1 is a vertical section through the type writercabinet. Fig. 2 is a detail longitudinal section of one side of thecabinet on the line 2 2 of Fig. 1, looking inward. Fig. 3 is an enlargeddetail perspective of the connection between the cover and the levers.Fig. 4 is an enlarged detail perspective of the friction wheelsattachedto the rear of the cover. Fig. 5 is an enlarged detailperspective of the connection of the lever to the leaf or base.

In the drawings the numeral 1 designates the case or cabinet which maybe of any approved form, dimensions and arrangement. Within the case toopposite walls thereof in any suitable manner I pivot two levers 2, eachhaving a short arm 4 and long arm 5 made by the point at which thelevers are pivoted to the walls of the cabinet, the pivot pins 3 of 5othe two levers being preferably cast integral with the plates 6 whichare secured by screws or otherwise to the opposite sides of the case.

To the ends of the short levers4 is pivoted vthe leaf or base 7 whichsupports the type writer, the connection between said leaf and leversbeing made toward the-rear of the leaf on opposite sides thereof and bymeans of pivot pins 8 extending from plates 9 which are screwed orotherwise secured to the opposite side `of the leaf.

To the ends of th'e long arms of the two levers is pivoted or hinged thetop 10 of the cabinet, the pivoting or hinging being effected by meansof pivot pins 11 which are formed on the plates 12 which are screwedorotherwise secured to the rear portion of the top or cover on oppositesides thereof as illustrated. These plates l2 are formed with stops orshoulders 13 which lie back of thev rear edges of the levers 2 and atone point in the downward movement of the top or cover bear against thelong arms so as to prevent the rear or lower edge of the cover beingthrown forward so as to strike or interfere with the type writer carrieddownward with the base or leaf. These stops or shoulders also bearagainst the long arm at a point in the upward movement of the top orcover and tend to exert a forward pressure on said arm and thus aid inthe movement of said levers.

To the rear opposite corners of the top orv cover I attach frictionwheels or rollers 14 which in the forward and backward movement of thetop or cover bear against the track or rails 15 secured to the rear ofthe case at opposite corners, and the lower portion of which curvesinwardly so as to throw the rear end of the top or cover inwardly whenin its poised position and thus bring the front piece 16 of the coverclose to the rear of the leaf or base to the type writer.

I may attach friction rollers 17 to the inside walls of the case nearthe front of the caseY or other appropriate place so that they will lieover the side edges of the leaf or base for the type writer-and thusassist in guiding the same. I also attach a suitable stop or stops 18 tothe sides of the interior of the case so that the long arms of thelevers will come against the same after the type writer base or leaf hasbeen tilted and carried downward sufficiently to take it wholly withinthe case, these stops 18 thus limiting the movement of the levers andcausing the type writer to stand IOC at the most convenient point withinthe case and permit the top or leaf to turn on its pivot or hinge so asto lie in a horizontal position and form a portion of the fiat top ofthe top of the case. I also form recesses 19 in the under face of therear top portion of the case so that when the top is in its horizontalposition the friction wheels or rollers 14 will lie in said recesses.

The bottom of the caseis preferably formed of an inclined board 20 thetop edge of which may constitute a rest for the front piece 16 of thetop.

In operation the type writer rests upon the leaf or base 7, the feet ofthe type writer fitting in sockets or holes formed in the base so as toreceive the same and suitable clamps in addition may be used to hold thetype writer in place. Assuming that the type writer base orleaf is inits horizontal position andit is desired to close up the cabinet, thehandle 2l of the top is grasped by the hand and an upward pull madethereon when the type writer leaf or base is tilted and as the pull iscontinued said leaf or base is then moved or carried downward and thetop or coverbrought over so as to close up the top of the cabinetwiththe type writer inclosed within the cabinet. The levers are soproportioned that the type Writer leaf orbase will stand at such aninclination that the type writer will not fallor tilt backward therefromwhen the leaf is in its inclined position; the parts being also soproportioned that the top or cover will at all times be free fromcontact with the type writer. This construction affords a very simplearrangement of parts which are efficient in operation to raise and lowerthe type writer with but little eort on the part of the operator. Theparts are also so few and so simple that they are very strong anddurable and not liable to get out of working order.

I have described with particularity what I consider to be the bestconstruction and arrangement of the several parts, but it is obviousthat changes can be made in details without departing from the essentialfeatures of my invention.

Having described my invention and set forth its merits, what I claimis- 1. The combination with the type writer case, of the type writerleaf or base, free to slide horizontally and tilt, rearwardly the top orcover adapted to move backward and downwardly inside the case, the sidelevers having each a long and a short arm, the long arms of said leversbeing hinged to the top or cover and the short arms to the said leaf orbase whereby as the top is thrown back and down inside of the case theleaf will be caused to slide and tilt, and stops or shoulders adapted tobear against the long arms of the levers as the top is thrown back anddown inside the case and thus prevent the top coming in contact with thetype writer, substantially as and for the purposes described.

2. The combination of the tilting and slid ing type writer leaf or base,the top or cover, the levers having their short arms connected to thebase or leaf and their long arms to the top or cover, the frictionwheels or rollers attached to the rear of the top or cover, and thetrack or rails curved inwardly at their lower ends for the said wheelsto run upon, substantially as and for the purposes described.

3. The combination of a tilting and sliding type writer leafor base, thetop or cover, the levers having a top or cover attached to the long armsthereof and the leaf or base to the short arms, the shoulders or stopsattached to the top or cover and adapted to bear against the long arm ofsaid levers, the stop to limit the forward movement of the long arms orlevers, the friction wheels or rolls attached to the rear of the top orcover, and the tracks or rails for said wheels to run upon,substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY TROST.
